Five-port USB 3.2 Gen 2 card for desktop PCs

This EN-Labs expansion card adds three USB Type-C and two USB-A ports to a desktop computer through a PCIe x4 slot. It suits users who need extra high-speed ports for external drives, docking stations or charging devices without replacing their motherboard.

Passive cooling with on-board power regulation

The card draws all required power directly from the PCIe bus and uses ASMedia ASM3142 and VL822 controllers to manage two shared 10 Gbps lanes plus one dedicated 10 Gbps lane. No auxiliary power connector or active cooler is present, so operation stays silent inside the chassis.

Fits any x4 x8 or x16 slot with full-height bracket

A full-profile slot cover is included and the board works in x4, x8 or x16 slots but not in x1 slots. Driver-free installation applies to Windows 8, 10 and 11 while Windows 7, Vista and XP require the supplied driver CD. Mac OS 10.8.2 and later and Linux are also supported.

Questions about this item

How do I install this PCIe x4 card and which slot mistake should I avoid?

Insert the card into a PCIe x4, x8 or x16 slot; do not use a PCIe x1 slot because it is not supported.

What power-related maintenance might this card need later?

The card draws power directly from the PCIe slot with no extra connector, so no power-supply maintenance is required.

What bandwidth limit appears first when all five ports run at once?

Two USB-A and two USB-C ports share a 10 Gbps pool, so combined traffic on those four ports hits that ceiling first.
